H3K27ac monoclonal antibody

Figure 1. ChIP results obtained with the Diagenode monoclonal antibody directed against H3K27ac
ChIP was performed on sheared chromatin from 500000 HeLa cells using 0.5 µg of the Diagenode antibody against H3K4me3 (cat. No. C15410003) as described above. The IP'd DNA was subsequently analysed on an Illumina NovaSeq. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 50 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the complete sequence and a 2 Mb region of the human X-chromosome (figure 2A and B) and in two regions surrounding the GAPDH and EIF4A2 positive control genes, respectively (figure 2C and D).

Figure 2. ChIP-seq results obtained with the Diagenode monoclonal antibody directed against H3K27ac
ChIP was performed on HeLa cells using 0.5 µg of the Diagenode antibody against H3K4me2 (cat. No. C15410035). The IP'd DNA was analysed on an Illumina Hiseq. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 51 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the complete sequence and a 1.5 Mb region of the human X-chromosome (figure 2A and 2B) and in 2 chromosomal regions surrounding the ACTB and GAPDH positive control genes (figure 2C and D, respectively).

Figure 3. Cross reactivity tests using the Diagenode monoclonal antibody directed against H3K27ac
To test the cross reactivity of the Diagenode antibody against H3K27ac (cat. No. C15210016), a Dot Blot analysis was performed with peptides containing other histone modifications and the unmodified H3K27. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:2,000. Figure 3 shows a high specificity of the antibody for the modification of interest.

Figure 4. Western blot analysis using the Diagenode monoclonal antibody directed against H3K27ac
Western blot was performed on whole cell extracts (40 µg) from HeLa cells using the Diagenode antibody against H3K27ac (cat. No. C15210016). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is shown on the right, the marker (in kDa) is shown on the left.

Figure 5. Immunofluorescence using the Diagenode monoclonal antibody directed against H3K27ac
HeLa cells were stained with the Diagenode antibody against H3K27ac (cat. No. C15210016, red) diluted 1:1,000. Actin was stained with fluorescein phalladoin (green).
